Need help in understanding Newton's third law of motion:
As per his third law " For every action, there is an equal and opposite reaction".

Let us take the following example. There is a tennis ball on a table. If i apply a certain amount of force (pushed by hand), the ball moves in the direction of force applied(as per first two laws).

Now what is the action here and what is the reaction.? As the ball have moved we dont feel any opposite force. Then what about the third law here..?

the ball pushes back on you.

you feel it in your hand.

hit it hard enough and it will hurt.

My doubt is, if the reaction force the ball applies on us is equal based on the third law then the ball should not move. But the ball is moving. How can we explain the third law here?

Newton's 3rd:  the forces are equal and opposite.  

BUT your force on ball makes it accelerate.

AND its force on you, were you floating in outer space, would make you float away (accelerate) in the other direction.

as it happens, you are not in outer space.  you are "grounded" to earth.  effectively tied to it by gravity and friction.
